TU RN-TABLE FOR MOLDERS.

SPECIFICATION forming part of Letters Patent No. 397,684, dated February12, 1889,

Application filed October 5, 1888,

To a 1071 0722 it may concern:

Be it known that we, STEPHEN ALLEY and JOHN ALEXANDER MACLELLAN,subjects of the Queen of Great Britain and Ireland, residents inGlasgow, in the county of Lana-rk, Scotland, have invented an ImprovedTurn- Table to be used by Founders and others, of which the following isa specification.

Our improved turn-table has been designed to be used in connection withrapid-molding apparatus, (such, for example, as that described in thespecification accompanying our application for Letters Patent of theUnited States filed August 29, 1888, Serial No. 28 i,Oi1,) and it isintended to be placed between the molding apparatus and the place atwhich the filling of the molten metal into the mold is to be effected.The turn-table is circular and is made with a platform on which workersmay stand, with an annular ledge or table on which the mold-boxes are tobe carried, and with acentral table to carry cores 01' other articles,such central table being made so as also to serve as ahandwheel, bymeans of which the turn-table can be turned.

The constructive details are hereinafter described with the aid of anaccompanying sheet of explanatory drawin Figures 1 and 2 of the drawingsare respectively a plan and a vertical section of the turn-table.

The turn-table is placed partly in a shallow pit, A, being carried by abed-plate, l3, fixed at the center of the bottom of the pit. In thebed-plate B there is fixed a central pillar, C, partly indicated bydotted lines in. Fig. 2, and onthis pillar there is fitted, so as to becapable of turning on it, a tubular piece, I), forming the main centerof the turntable, the frame-work of which is built upon it and iscomposed of radial horizontal girders E, of steel or iron, and inclinedstruts and ties F.

On the frame-work E F there is fixed a platform, G, of sheet-iron. Acylindrical rim,

1-1, is combined with the rest of the framemade with a spindle extendingabove the platform G, and indicated by dotted lines in Eierial No.287,346. (No model.)

Fig. 2, and on this spindle there is setatubular boss, L, which hasfixed at its upper end a small circular table or disk, M, made with arim, by means of which. it can be turned.

()n the lower part of the boss L there is a pinion, N, which gears witha spur-whee], I, on the upper end of a vertical shaft, Q, carried inbearings in the frame-work of the turn-table, and having at its lowerend a pinion, R, in gear with a spur-wheel, S, fixed on the stationarycentral pillar, C. By means of this gearing the entire turn-table ismoved slowly round, when the small central table, M, is turned by aworker standing on the platform G.

In using our improved turn-table the moldboxes are successivelytransferred from the molding-machine onto the annular ledge K, and theturn-table is moved round at intervals through short distances, a workeron the turn-table putting in cores, if required, and turning the smalltable M. being thus carried round step by step, move in succession intothe position for filling them, and are carried onward to a position.where they are removed or otherwise dealt with.

'hat we claim as our invention is l. A turn-table constructed to turn ona central fixed pillar and comprising, in combination, a frame-work, aplatform, a raised annular ledge or table, a central small table adaptedto carry cores, &c., and gearing connectingthe said central table withthe turn-table, whereby a person standing on the turn-table may revolvethe latter by turning the central table, substantially as herein setforth.

2. A turn-table with the gearing for turning it, consisting of a centralrimmed table or disk, a pinion fixed to the center boss of the table ordisk, a vertical shaft carried by the turn-table and having on it aspur-wheel gearing with the said pinion, and a pinion on the verticalshaft gearing with afixed spur-wheel, substantially as herein described.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
